How to do, how to determine and control warehouse humidity

Warehouse temperature humidity is how much, most of the warehouse stock is cardboard box, easy to become soft and damp. So what is the temperature humidity that the carton should keep?

In addition, if the humidity is too big, how should deal with?

Knowledge of temperature and humidity management in warehouse

As an important aspect of warehouse management, the temperature and humidity management of warehouse is very important.

Need to master the relevant knowledge of air temperature and humidity.

Determination of temperature and humidity in warehouse:

Dry wet - bulb thermometer is used for the determination of air temperature and humidity.

Outside the library, in order to avoid the sun, rain, dust invasion, the wet and dry tables should be placed in the screen.

The ball of the thermometer in thermometer screen is 2 meters above the ground level.
The door of shelters shall be placed in the north to prevent direct sunlight from being observed.

The box should be kept clean, no sundries, so as not to cause air circulation.

In the library, the dry and wet meters should be placed in the air circulation, not exposed to the sun.

Don't hang on the wall. it's about 1.5 meters above the ground.
Daily monitoring and recording of temperature and humidity in the library must be conducted on a daily basis. Generally, from 8 a.m to 10 a.m, and from 2 p.m to 4 p.m. Record the data to be properly preserved, regular analysis, take out the law, in order to grasp the initiative of commodity preservation.

Control and regulate the temperature and humidity of the warehouse:

In order to maintain the quality of the warehousing goods and create an environment suitable for commodity storage,
When the temperature and humidity of the warehouse are suitable for commodity storage, we should try to prevent the adverse effects of the outside climate on the library.

When the temperature and humidity in the library are not suitable for commodity storage, it is necessary to take effective measures in time to adjust the temperature and humidity in the library.

Practice has proved that the combination of seal, ventilation and moisture absorption is an effective way to adjust the temperature and humidity in the library.

Sealed commonly used methods include whole warehouse seal, small chamber seal, according to seal, and by shelf, according to the seal and so on.

Ventilation

Ventilation is the air pressure difference formed by the different air temperature inside and outside of the library, which makes the air form convection inside and outside the reservoir to achieve the purpose of adjusting the temperature and humidity in the library.

The larger the temperature difference inside and outside the library, the faster the air flow. If there is wind outside the library, the pressure of wind can accelerate the convection of the air inside and outside the library.

But the wind cannot be too big ( more than 5 wind, more dust ).

Properly ventilated, not only can adjust and improve the temperature and humidity in the library, but also timely distribute the surplus water of goods and packaging materials.

According to the purpose of ventilation, it can be divided into two kinds: ventilation cooling ( or warming ) and utilization of ventilation.

absorption of moisture

In the rainy season or rainy weather, when the humidity of the library is too high, not suitable for commodity storage, and the external humidity is too large, it is not appropriate to carry out the ventilation and disperse tide, can use moisture absorption method to reduce the humidity inside the storehouse.

The warehouse of many large retail enterprises, the general use of mechanical moisture absorption method. Use xishiji to put the wet air in the library through the suction fan, and suck it into the xishiji cooler to condense it into water.
